BURNISHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 433,387, dated July 29,1890. Application filed April 8, 1890. Serial No. 347,080. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES J. ADDY, of l\lalden,county of Middlesex,State of Massachusetts, have invented an Improvement inI-Ieel-Burnishing Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

My invention is shown as embodied upon that class of heel-burnishin gmachines known as the Tapley, and illustrated in United States PatentNo. 328,371 and many others.

The herein-to-be-described improvements comprehend means for moving theboot or shoe support toward and from the heel-rest.

V In accordance with this invention a block having an inclined face ismoved at substan tially right angles to the shoe-support, the inclinedside or face acting on the said support to move it against the tensionof a spring, which latter, as the said block retreats, restores the saidrest to its normal position. This block is moved positively in onedirection by means of a cam, and although it may be restored in manyways I prefer to restore it positively, and hence I have provided thecam with a groove, in which a pin attached to the block slides, saidcam-groove describing a curved path eccentric to the axis upon which thecam turns, so as to both raise and lower the said block in turn. Asuitable hand-piece is provided for turning the cam to move the block.

Figure 1 shows a portion of a jack of a heelburnishin g machine providedwith a shoe-support and heel-rest andmeans comprehending this inventionfor moving said shoe-support; Fig. 2, a longitudinal section of the shoesupport and a portion of the jack, the block for moving the shoe-supportand the cam being shown in elevation; Fig. 3, a rear view of the partsshown in Fig. 1, the shoe-support being taken in section.

The jack a of the heel-burnishing machine is formed to furnish aheel-rest b and bearings for the 'shoesupport b to contact with theinner side of the sole at the heel. This shoe-support consists of a rodor bar having a longitudinal movement in its bearings, and

is encircled by or acted upon by a spring b the tendency of which is tokeep it in retreated or withdrawn position. The rod or bar I) has a holeor slot 1) through it. (See Fig. 2.) A block cl, having an inclined face61', (see Fig. 2,) is arranged to slide vertically in suitable bearingsin the jack on, the upper end of said block passing through the hole 19in the shoe-support Z), which hole also has an inclined side or face.This block d has at its lower end a vertical slot or guideway 01 for aguide-pin (F. The block is forked at its lower end to stride a cam-diska, mounted to be turned on said pin (1 as a pivot. The outer peripheryof this cam-disk 6 describes a curved path eccentric to the axis ofrotation of the disk, and, as herein shown, the block rests on saidperiphery, so that as the cam is turned in one direction it will belifted, and is turned in the other direction it will fall by gravity, ifother means Which will be now described were not provided.

The block (1 has projecting inwardly from the forked end a pin 2, whichenters the groove 3 in the cam-disk c. This groove 3 describes a curveeccentric to the axis of rotation of the disk, or is a small cam. As thecam is turned in one direction it will act on and raise the block (Z,and as the cam is turned in the other direction the pin moving in thegroove will restore the block cl to its normal position. It is obviousthat the pin 2 may be made of sufficient strength to eflect the raisingof the block D. The cam e is provided with alimiting-stop e, whichstrikes against one side of the block d when the cam has been turned toraise the block to the proper height. As the block is raised, theshoe-support Z) will be moved in the direction of the arrow, Fig. 2, andas the block is restored to its normal position the spring b willactuate the said support in the opposite direction.

A hand-piece f is secured to the cam-disk, by which it may be turned inone or the other direction by the operator.

. I claim- 1. In a heel-burnishing machine, a normallyretraetedshoe-support, a spring to control it, and a block movable at an anglewith relation to the said shoe-support and having an inclined side toact an and move said support against the action of the spring, combinedwith a rotatable cam for moving the said block, substantially asdescribed.

2. In a heel-burnishing machine, a slotted shoe-support, a block havingan inclined face to enter said slot and move the support, comport, ablock having an inclined facefor moving it, and having the pin 2,combined with a cam-grooved disk and means for'tnrning it, substantiallyas described.

In testimony whereof I have signed. my name to this specification in thepresence of two subscribing Witnesses. bined with a cam for moving saidblock toj ward and from the shoe-support, substan- [o tially asdescribed.
